Abstract
Description
- The present, invention relates to a seat belt for protecting automobile passengers during collisions, and more particularly to an air belt having a bag-like portion, which is inflated by gas generated by a gas generator.
- Japanese Unexamined Patent Publication No.5-85301 describes a typical inflatable safety harness. Fig.12(a) is a perspective view showing the inflatable air belt. Fig.12(b)is a cross sectional view of the air belt shown in Fig.12(a) taken along line B-B.
- An air belt device 1 includes a
shoulder belt 2, alap belt 3, a buckle 4, atongue 5, and anintermediate guide 6. Theshoulder belt 2 extends diagonally from the right side of a passenger's body to the left side. Thelap belt 3 extends across the passenger's body from the right to the left. The buckle 4 is secured to a floor, or the like of the vehicle body. The intermediate guide guides theshoulder belt 2. - The
shoulder belt 2 has anordinary belt 2a similar to the conventional seat belts, and a bag-like belt portion 2b attached to one end of thebelt 2a. Theintermediate guide 6 slidably supports thebelt 2a. The other end of thebelt 2a is connected to an emergency locking retractor (ELR)7,which is secured to the automobile body The ELR winds and retracts thebelt 2a. - The bag-
like belt portion 2b engages with the passenger's body when in use. It has thetongue 5 at its free end opposite to the end that leads to thebelt 2a. - The
lap belt 3 is an ordinary and commonly available belt. One end of thelap belt 3 is connected to thetongue 5 while the other end of the belt is connected to the ELR 8,which is secured to the automobile body. The buckle 4 has a gas generator 9 to generate a high pressure gas upon accidents such as collisions. - A passage extends through the
tongue 5 and the buckle 4 to allow flow of gas from the generator 9. - As shown in Fig.12b, the bag-
like portion 2b of theshoulder belt 2 includes a foldedbelt body 2c, as indicated by solid lines, and is enclosed in acover 2d, the two edges of which are sewn to each other to formstitches 2e. Accordingly, the structure of the bag-like portion has a strap-like shape. Upon activation of the gas generator 9, thestitch 2e tears as theshoulder belt 2 inflates, and the bag-like portion 2b expands as shown by the double dotted line. - Employing a retractable webbing, which is attached to one end of the shoulder belt and is wound by a retractor, the air belt device described in Japanese Unexamined Publication No.5-85301 ensures a large degree of freedom with respect to the passenger's upper body movement, where the webbing extends and retracts in response to the movements of the passenger. It would be required, however, that the winding force of the
retractor 7 in the air belt in Japanese Unexamined Publication No.5-85301 not be too strong to prevent the belt from pressing the passenger with excessive force. Due to the limitation on the winding force, the gap arises between theshoulder belt 2 and the passenger's body, requiring further expansion of the bag-like portion 2b upon a collision. - Accordingly, it is an objective of the present invention to provide an air belt device that works without applying excessive force on the passenger's body.
- The present invention provides an air belt: device. The air belt device includes an inflatable air belt and a gas generator for supplying gas to the air belt to inflate the same. The air belt has a bag-like belt folded in a strip-like state and a cover for covering the bag-like belt. The air belt device being characterized in that the gas releasing means gradually releases the residual gas in the air belt after the inflation of the air belt by the gas generator.
- The gas releasing means gradually releases the gas from the air belt to reduce the impact that applies on the passenger upon a collision.
- The features of the present invention that are believed to be novel are set forth with particularity in the appended claims. The invention, together with objects and advantages thereof, may best be understood by reference to the following description of the presently preferred embodiments together with the accompanying drawings in which;

-
- An embodiment according to the present invention will now be described with reference to the drawings. Fig. 1(a) is a perspective view showing an automobile seat with an embodiment of an air belt device according to the present invention. Fig. 1(b) is an perspective view of the air belt device. Fig. 2(a) is a plane view showing the region around the joint between a shoulder belt and a lap belt, and Fig. 2(b) is a plane view showing a bag-like belt portion. Figs. 2(c), 2(d), 2(e) are cross-sectional views taken along lines C-C, D-D, E-E, respectively in Fig. 2(a). Fig. 3(a) is a plane view showing the shoulder belt that is inflated. Fig. 3(b) is a plane view of the bag-like portion that is inflated. Figs. 3(c) and 3(d) are cross-sectional views taken along lines C-C and D-D respectively in Fig. 3(a). Fig. 4 shows weaving patterns of an air belt cover.
- Since the air belt device according to the embodiment is essentially the same as the air belt device shown in Fig. 12 except for a bag-
like portion 2B that comprises ashoulder belt 2, the arrangements of theair belt 2B will mainly be discussed. - As can be seen in Figs. 2 and 3, the
air belt 2B includes a bag-like belt 10 and atubular knit cover 12 enclosing the bag-like belt 10. The bag-like belt 10 has a greater width in the part that fits to the passenger's body over the region from the chest to abdomen. The enlarged portion is folded on top of itself to form a long band shape as shown in Fig 2. - The
knit cover 12 has considerable elasticity in the direction perpendicular to the belt's longitudinal direction whereas it virtually doesn't expand longitudinally. The weaving patterns of the knit cover are shown in Figs. 4(a), 4(b) where Fig. 4(a) shows a simple warp knit pattern and Fig. 4(b) shows a pattern into which inlay threads are introduced to increase the strength and allow the thinner structure. Either pattern can be used in the present invention. Theknit cover 12 is made virtually unexpandable in the longitudinal direction by applying the thermal expansion process. - The
air belt 2B andlap belt 3 are sewn to each other. Both the bag-like belt 10 andknit cover 12 are sewn to thelap belt 3. Theknit cover 12 is sewn to awebbing 2a as well as to atongue 5 to reduce the tension that acts on the belt. - Since all the other features of the embodiment but the points described above are essentially the same as the air belt device shown in Fig. 12(a), the
air belt 2B inflates when a gas generator 9 is activated with thetongue 5 engaging with the buckle 4. Upon the activation of the gas generator 9, theknit cover 12 contracts in the longitudinal direction of theair belt 2B, causing thebelt 2B to tightly fit on the passenger. - Figs. 13 and 14 show how the
knit cover 12 contracts longitudinally when theair belt 2B, or bag-like belt 10 inflates. As was mentioned above, theknit cover 12 is made virtually unexpandable in the longitudinal direction of the belt by means of the thermal expansion process. When thebelt 10 inflates, the knitted loops of theknit cover 12 expand in the direction perpendicular to the longitudinal direction of the belt. This shortens theknit cover 12 longitudinally, and consequently theair belt 2B. - Embodiments of a tongue and a buckle that can preferably be employed in the present invention will now be described with reference to Figs. 5 through 11.
- Figs. 5 through 8 show the first embodiment of a tongue and a buckle. Fig. 5(a) is a cross-sectional view showing a
tongue 14 and abuckle 16. Fig. 5(b) is a cross-sectional view taken along line B-B in Fig. 5(a). Fig. 6 is a perspective view of the upper part of the embodiment. Fig. 7 is a perspective view showing the whole of the tongue and buckle joined together. Figs. 8(a) and 8(b) are enlarged cross-sectional views of the joint. - The
tongue 14 has atongue base 18, aseal 20, atongue plate 24, ananchor 26, aring 28, aplastic cover 32, and so on. Thetongue base 18 has an internal cavity. Theseal 20 closes the front end of thetongue base 18. Thetongue plate 24 andanchor 26 are connected to thetongue base 18 by connectingpins 22. Thering 28 attaches theair belt 2B to thetongue base 18. Theplastic cover 32 encloses thetongue base 18. Theseal 20 is provided with atear line 33. - When the
tongue plate 24 is inserted into thebuckle 16 through a port 34 ( Fig. 6 ), a latching pin of alatch mechanism 38 inside thebuckle 16 is locked in a latchinghole 36. By pressing abutton 40 on thebuckle 16, one can unlock the latch and subsequently release thetongue plate 24 from thebuckle 16 with a help of a spring. - The
anchor 26 has aport 42 through which the tip of thelap belt 3 is inserted and is connected to theanchor 26. - The
buckle 16 has a shell comprising ahousing 46, on the top surface of which are provided theport 34 for the insertion of thetongue plate 24 and agas port 48. - The
gas port 48 is sealed with theseal 50 having atear line 52. - Inside the
housing 46 are provided aduct 56 and aninflator 58. Aflap 54 is pivotally supported at an end of theduct 56 and can be opened. - When the inflator 58 is activated, the
flap 54 pushes theseal 50, causing theseal 50 to tear apart along thetear line 52. Subsequently, theseal 20 breaks apart along thetear line 33 and the gas is supplied to theair belt 2B, inflating theair belt 2B immediately. - Though the embodiment features the
seal 50 that is inclined to prevent dust from accumulating on it, it is also possible to have aseal 50A with a level upper surface as shown in Figs. 9 and 10. - Figs. 9 and 10 show a second embodiment of a tongue and a buckle. Fig. 9 shows those under normal operation , and Fig. 10 shows the condition where the inflator is activated. Figs. 9(a) and 10(a) are perspective views showing upper parts of the buckle 16'. Figs. 9(b) and 10(b) are cross-sectional views showing the joints between the tongue and buckle.
- In Figs. 9 and 10, it can be seen that a
cylinder 60 with aflap 62 is placed in the buckle under theseal 50A. Thecylinder 60 is connected to aduct 56 via astopper 64. The other reference numbers in Figs. 9 and 10 correspond to analogous parts in Figs. 6 and 8. - When the inflator 58 is activated, the
cylinder 60 moves forward (upward). This breaks theseal 50A and subsequently, theseal 20. Theflap 62 then opens up in thetongue base 18 to permit the gas flow into theair belt 2B. At this point, flaps 20F and 50F resulting from the breakage of theseals tongue base 18 at its entrance, preventing gas leakage. - Figs. 11(a), 11(b), and 11(c) are cross-sectional views of the third embodiment of a tongue and a buckle. In this embodiment, vents 70 are further provided to the embodiment described in Figs. 9 and 10. The vents are formed at the tip of the tongue. Upon the activation of the inflator, flaps 20F and 50F cover up the
vents 70 as shown in Fig. 11(b), allowing the gas to flow into theair belt 2B and inflate it. As the amount of the gas generated by the inflator decreases, the pressure inside theair belt 2B exceeds the pressure of the incoming flow, which causes theflaps vents 70 open up to let the gas in theair belt 2B out gradually. The gradual release of the gas from the belt minimizes the impact that applies on the passenger's body when the body is pressed against the belt upon a collision. - As described above, the air belt device according to the present invention provides an air belt that can comfortably be fastened on the passenger's body while it protects the passenger upon collisions by means of shortening. The impact applying on the passenger's body can be reduced significantly by providing vents to gradually release the gas after the completion of the belt inflation.
